activate. This alarm limit is enabled by the Shallow Alarm Active
selection of
YeS.
Alarm
If
No Data - Allows you to receive an audible and visual alarm if
NMEA 0183 data is not being received on the data port at regular
intervals (typically every few seconds). The available choices are
Yes and No (default).
Input Sentence - Specifies the NMEA 0183 data sentence to read the
depth data from. The available choices are Any (default), DPT,
DBS, DBT, or DBK sentence. It is better to specify the appropriate
sentence because more than one method of reporting depth may
be available on the port.
The window in the lower portion of the screen allows you to see the
depth data that is received on the data port (Input:) and the data that
is actually displayed inNAV 4 (Used Value:).

DGPSMode:
Auto - sets the receiver to automatic DGPS or GPS modes. This is
the default setting. IfDGPS corrections are being received and
their age is less than the Max Age limit, the receiver will oper-
ate in DGPS mode (assuming you are receiving corrections for
enough satellites to operate in DGPS mode). Otherwise, the
receiver operates in GPS positioning mode.
The traffic light will be green when it is in DGPS mode.
